Google Opens SynthID AI Detection Tool to the Public Amid 1 Million Daily Requests

Google has publicly launched a web-based SynthID Detector that allows anyone to verify if images, audio, or video were generated by AI. The platform processes 1 million verification requests daily and supports dozens of file types ranging from MP4 and WEBM to FLAC and HEIC. Generative models including Nano Banana, Veo, and Lyria automatically apply the SynthID watermark to their outputs. The SynthID standard is currently supported by OpenAI, NVIDIA, and Kakao, with Apple reportedly preparing to integrate it. Competitors Microsoft and Meta maintain their own proprietary watermarking standards, which reportedly struggle to consistently identify content created by their own models.
